Jeff, what you are describing is in works and actively discussed https://cwiki.apache.org/confluence/display/NIFI/Extension+Registry and https://cwiki.apache.org/confluence/display/NIFI/Component+documentation+improvements
The last one may not directly speaks to the “ExtensionRegistry”, but if you look through he comments there is a whole lot about it since it is dependent. Feel free to participate, but I can say for now that it is slated for 1.0 release.

Since flow.xml.gz is generated automatically and it is saved in a compressed file, I am wondering what would be the best practice regarding version control?
